Instructions

- Move the "mirror line", which we call the Line of Reflection in our class, to the appropriate location to answer the questions below.

1. Line of Reflection: Y-axis

What happens to the coordinates of the vertices of the shape after a reflection about the y-axis?

2. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.

Reflection about the y-axis: (x, y)

5. Line of Reflection: y = x

What happens to the coordinates of the vertices of the shape after a reflection about the line y=x?

6. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.
